public abstract void onFrameRendered (MediaCodec codec, 
                long presentationTimeUs, 
                long nanoTime)

Called when an output frame has rendered on the output surface.

Note: This callback is for informational purposes only: to get precise render timing samples, and can be significantly delayed and batched. Some frames may have been rendered even if there was no callback generated.

Parameters
codec MediaCodec: the MediaCodec instance

This value must never be null.

presentationTimeUs long: the presentation time (media time) of the frame rendered. This is usually the same as specified in MediaCodec.queueInputBuffer(int, int, int, long, int); however, some codecs may alter the media time by applying some time-based transformation, such as frame rate conversion. In that case, presentation time corresponds to the actual output frame rendered.

nanoTime long: The system time when the frame was rendered.
